jismart2023028: Passive Low Energy Research on Hangzhou Convention and Exhibition Buildings

Abstract

Under the goals of carbon peak and carbon neutrality, the issue of high energy consumption in large-scale exhibition buildings has become a hot topic in the field of architectural design. The layout courtyards, influenced by orientation and window-wall ratio, directly impacts the level energy consumption. By selecting 12 well-known exhibition buildings both domestically and as research subjects and using scatter curve, it was discovered that there exists a nonlinear quadratic function relationship between the standard area and courtyard area. Based on function relationship, four typical layouts were. Taking the climate conditions the Yangtze River Delta region, represented by Hangzhou, as a basis, Design Builder software was utilized to simulate the energy consumption of the four typical layouts and analyze the influence of factors such as window-to-wall ratio and orientation on energy consumption. The study found that there is a window-to-wall ratio that minim energy consumption in exhibition buildings, and L-shaped courtyards facing south and U-shaped courtyards facing east are more energy-efficient. This research provides a reference for designing exhibition buildings with low energy consumption and good indoor-outdoor interaction.
